This document discusses Freud's structural model of the psyche and various defense mechanisms. It explains that Freud believed the psyche is composed of the id, ego, and superego. The id operates on the pleasure principle, the ego operates on the reality principle, and the superego contains our moral values. It then defines and provides examples of common defense mechanisms like repression, regression, displacement, denial, projection, rationalization, and sublimation that the ego uses to reduce anxiety. The document concludes with an activity instructing groups to create and act out a scenario demonstrating different defense mechanisms.
